Geometry: Angles at a Point
• Introduction

Remember

The angles around a point add to 360°

So the missing angle = 360° - 25° - 105° - 90º = 140°

• Question 1

Three of the four angles around a point are 70º , 60º and  65º.

Work out the size of the fourth angle in degrees.

(Just write the number)

• Question 2

Three of the four angles around a point are 75º , 90º and  65º.

Work out the size of the fourth angle in degrees.
